three-phase version. Moreover, each operator is available in the fast version
with a 4 pole motor (ULISSE S C - ULISSE S CM - ULISSE S SB).

G) Adjustable fixing bracket
3) TECHNICAL SPECIFICATIONS
See Table 1
4) OPERATOR INSTALLATION
Preliminary checks:
• Check that the door is perfectly balanced.
• Check that the door slides along its entire stroke.
• Check the safety devices (parachute, cables etc.).
• If the door is not being installed for the first time, check all its components
for wear.
• Repair or replace any faulty or worn parts.
• The operator reliability and safety are directly affected by the condition
of the sectional door structure.
5) PREPARATION OF OPERATOR (for ULISSE C/CM only)
For C and CM models, you must complete the closed chain loop which allows
the operator to be released by means of a winch. To do so, you only need to
open the end rings from both sides of the piece of chain coming out of the
operator, and complete the loop using the chain available inside the pack.
Then close the rings which were previously opened taking care to realign
the chain ends. Finally check that the joints are well formed by making them
slide a few times inside the operator in both directions.
6) OPERATOR INSTALLATION
The operator can be installed either on the left or on the right of the sec-
tional door.
Direct drive (for all versions)
The cable-winder shaft of the sectional door (Ø=1ln Ø25,4 mm) must be
provided with a keyway (Fig. 2 “C”) and can be inserted directly into the
operator through shaft. The operator is directly fastened to the wall using
the appropriate bracket (Fig. 2 “G”). Some manufacturers of sectional doors
supply joints with shaft, suitable for these types of operators.
For the SC, SCM and SSB models, this type of installation can be carried
out on sectional doors with cable winders, having a diameter not greater
than 80 mm in order to respect the maximum speed and therefore impact
force prescribed by current standards.
Reduced drive (ULISSE SC-SCM-SBS only)
Motion is transmitted to the cable-winder shaft by means of a chain drive,
which may be provided with reduction ratio (Fig. 3).
WARNING:
The chain drive must be protected
in compliance with the
current standards
(Fig. 3 “P”).
The gearmotor is fastened to the wall by means of the bracket supplied
(Fig. 3 “G”).
The drive dimensions must be in accordance with the impact curve prescribed
by the current standards.
For this type of installation, a shaft with an 18 tooth pinion for a 1/2” x 5/16”
simple chain (
Fig. 3
) can be supplied as an accessory.
Chain tension can be adjusted by moving the motor along the slots in the
anchoring bracket (Fig. 3 “F”).
7) ELECTRICAL INSTALLATION SETUP
Prearrange the electrical installation according to the relevant standards in
force.
The interconnecting cables must not touch the motor stator. The cables
should be kept at a safe distance.
The power supply connections must
be kept totally separate from the service connections (photocells, safety
edges, control devices etc.).
Warning! For the connection to the power supply, use a multipolar
cable having minimum 4x1.5 sq mm cross section and complying with
the previously mentioned regulations (for example, the cable must
be at least equal to H05 VV-F with a 4x1.5 sq mm
section). To connect
the auxiliary contacts, use cables with a minimum section of 1 mm
2
.
Warning!
Keep the low voltage connections that supply power to the motor
separate from the connections provided for the limit switches of the auxiliary
contacts (extremely low safety voltage) and use suitable cable-holders (Fig.
1 P1-P2).
Fit an omnipolar circuit breaker with at least 3,5 mm contact opening, pro-
vided with protection against overloads, suitable for cutting out the operator
from the mains.
The Sirio-FR and Mizar-FR panels are provided with a lockable switch and
cutout fuses (Fig. 5). A single/double-channel receiver for radio transmitter
can be inserted in the control panels.
Connection without control panel can only be carried out in case of single-
phase version and in presence of “hold-to-run” control on three-phase
versions (
Fig.6
).
Only use buttons having at least 10A-250V capacity.
WARNING: the power supply rating for the auxiliary contacts and
limit switch contacts must be the same.
8) TERMINAL BAR CONNECTION
The cables must be held in position using an extra fixing device in the
proximity of the terminals, e.g. with cable clamps.
WARNING: the connection of low-voltage safety accessories to
the three-phase Up version is not allowed.
WARNING: the power supply rating for the auxiliary contacts
and limit switch contacts must be the same. Mixed installation
is forbidden.
WARNING: extremely low safety voltage cables must be phisi-
cally separated from low voltage cables or be properly insu-
lated with an extra sheathing having a thickness of at least 1 mm.
Access to the electrical compartment or to limit switches must be al-
lowed to skilled personnel only.
Fig. 6 shows the connection of the single-phase (Fig. 6-A) and three-phase
(Fig.6-C) gearmotor to the terminal bar. For electrical connection to the control
panel, make reference to the respective instruction manual.

Connect the yellow/green cable to the earth terminal,
Fig. 4A
. The earth
cable length must be greater than that of the active cables.
9) CONNECTION TO TERMINAL BOARD
Fig. 6 shows the connection of the single-phase and three-phase gearmo-
tor to the terminal board.
For the electrical connection to the control unit, reference should be made
to the manual of the control unit.
10) LIMIT SWITCH ADJUSTMENT (fig. 10)
The limit switch unit is situated on the head of the drive and is the system
of adjustment. To gain access to the adjustment unit, dismantle the pinion-
type quick release system, if any, and the box which covers the unit.
The microswitches are activated by two toothed cams which are locked in
position by a holding spring.
When the door is closed, the “door closed” adjustment cam should activate
the closing limit switch.
When the door is open, the “opening” adjustment cam should activate the
opening limit switch.
Fig. 10 shows the position of the closing and opening limit switches in rela-
tion to the type of installation carried out.
If the adjustment cams are rotated towards each other, the stroke is in-
creased. If the adjustment cams are rotated away from each other, the
stroke is decreased.
The limit switch unit is equipped with a protection wedge “P” (fig.9) to pre-
vent damage to the limit switches during manual installation manoeuvres.
Remove it only when adjusting the limit switches.
11) ADJUSTMENT OF END-OF-STROKE MICRO
WARNING: For safety reasons, microswitch adjustment must be car-
ried out with the power supply off.
The adjustment unit features three microswitches: 2 for the limit switches
and 1 to provide safety against overstroke on opening.
The overstroke microswitch, if activated by the cam, stops the system com-
pletely. This may be caused by an incorrect connection or a faulty limiting
microswitch. If, during installation or maintenance, the cam intercepts an
overstroke microswitch, the system will not accept any commands: the cam
which intercepted the overstroke microswitch must be moved manually and
the reason why the microswitch was intercepted must be established. Also
make sure that the quick release mechanism or the manual chain-opening
